Application med March 27, 1918. Serial No. 225,052.

To all rwhom it may concern l Be it known that I, JAMES REGINALD. CrURGHILL, a subject of His Majesty the lim of England, and resident of Sheield, 1n t e county lof York, Kingdom of England, have invented a certain new and useful Vehicle-Wheel, of which the `following isa specification. i

My invention relates to wheels made entirely. of metal, for motor and other vehicles,

and has for its objects to cheapen Vand improve the construction of such wheels and to provide means whereby tires may be changed without the employment 'of hydraulic or.

other presses and without the necessity for llir removal of the entire wheel from its 4Arwheelconstructecl according to my invention comprises essentially two main portions, an outer portion and an inner or hub portion provided with respectively inwardly and outwardlyV directed spokes; anges or equivalent adapted toV be connected by a coned joint Vsituated intermediate of the outer portion and the inner or -hub portion. The outer portion is co-aXially mounted upon the hub portion (with or without an interposed medium as hereinafter mentioned) and there secured as by nuts or their equivalent.

` For such co-axial mounting 'Il employ a l wheel and tire in the plane A.of axis of the ortion and a correspondingly conedfsur ace or surfaces within the outer portion of the wheel (or vice versa) with bolts and nuts, studs and nuts or screws (hereinafter re- .I ferred to as bolts) to draw or force the two portions of the wheel with such a pressure 4 upon the coned surface "or surfaces (with or without an interposed medium as `hereinafter mentioned) that the resulting friction is sufficient to transmit whatever power may be required and thus to relieve the bolts of all shearing stresses. I make. no claim vto any frictional transmission of power between the coned. surfaces, as sucli" -transmission could always be performed by the bolts already mentioned.

Between the coned Surfaces of the inner and outer portions of the wheel constructed according to my invention I may employ any 'and frictional character-such as bolts and' a er ber, non-corrosive metal or woven fa in cases where it is desired to keep the metal surfaces from contact with eachotherand to insure that the two portions of the wheel are easily separable.

This interposed material 'eliminates any possibility of therustingtogether of the coned surfaces concerned and the interposed material may be employed either in one Patented Alma, raie.

piece orin two or more pleces'as convenient.-

Figs. 1 and 2 show a Wheel of which the hub portion 1 is provided with the coned 'part 2 (Fig. 1) on which fits the correspondingly coned part 3 of the outer por.-

The hubportion 1 and the outer portion 4, when secured together as described, form the com lete wheel. The outer portion 4 is shown tted with a single tire 8, which may either be vulcanized upon it or pressed upon it in the usual way. a

Fig'. 3 shows a wheel of which the outer portion 4 is modified to'receive a single tire 8 with a curved base. This `tire is vulcanized directly on the outer portion 4. The

hub portion is here shown'as made of pressed steel disks welded together.

Figs. 4 and 5 show a rea-r wheel comprising the hub portion 1 with the coned part 2 and the outer portion 4 with the coned part 3. The bolts 5 not only hold together the two portions of the wheel but also serve to carry the brake drum 9 (Fig. l). Interposedmaterial is shown at 10 between the cones 2 and 3.

Fig. 6 shows the outer portion of a wheel 4 provided with twin tires 8, 8 having curved bases. The cned part is shown at 3.

Fig. 7 shows a modilied form of outer portion 4 with coned part 3. This can be made as a casting (with suitable holes for the removal of the core) or it can be formed of light steel pressings suitably jointed by welding. This outer portion is shown held in position by the loose flange 6a and the screws 5.

Fig. 8 shows a modied form in which, for the sake of lightness, the circular continuity ofl the coned parts is interrupted and conical segments 21 and 3a are used instead. The approximately segmental flanges 6 receive the pressure of the bolts 5.

'Fig 9 shows a special form in which double conical parts 3b and 3b are formed on the outer portion and correspondin double conical parts 2b, 2b within the hu portion of the'wheel. of the pressed on type is shown.

The operations involved in molding and casting the two-portions of such a wheel as described are much more simple than those necessary for the production of an ordinary wheel in one piece; diliculties due to the contraction of the castings of ordinary wheels will disappear because thehub portion is much less in size and weight and the outer portion is less in weight than an ordinary cast wheel of equal strength and of ,a diameter and width of circumference to correspond with that of the outer portion of the wheel constructed according to my in vention. Also the spokes or flanges of the portions of my wheel are much less than the spokes of a wheel of equal diameter and made in one piece.

The wedging action of the cones multiplies the pressure of the bolts upon the conical surfaces ofthe two portions of the wheel and thus by intensifying the grip makes a very much more reliable and durable joint than can be obtained by equal bolts acting upon parallel surfaces.

The advantages of my invention are obtainable in their greatest degree by making the angle of the cones as acute as possible -consistent with their easy separation.

A certain amount of latitude is permissible 1n regard to the accuracy of machin- In this figure a tire l be correct in each of the two portions of the wheel, the necessary contact could always be secured by the operation of the bolts in drawing or forcing the coned surfaces together.

It will be seen that by the use and exercise of my invention, the outer portion of the wheel is suitable to receive the ordinary commercial pressed on tireor that it may form the base of a tire vulcanized. directly upon it. It will be evident that the position of the cones may be reversed inasmuch as that the inner cone may be part of the' outer portion and the outer cone may. be part of the hub portion of the wheel.`

It is obvious that the construction according to the present invention enables outer portions of different outer diameters and carrying tires of different sections and different diameters to be interchanged on a common inner or hub portion and further such interchange can be eected without removing the entire wheel from its aXle.

. I desire it to be understood that the forms of Wheel hereinbefore described other than the constructions shown in Figs. 3 and 6 may be used without a rubber tire or tires and that a tire vulcanized directly on the wheel or a pressed on tire may be used as desired.
